Cops caught two armed gunmen wearing surgical scrubs as the pair was in the middle of an illegal operation Saturday morning: robbing a Queens bank, officials and witnesses said.

Officers responding to a 911 call about the robbery at a Chase Bank on Union Turnpike near 178th Street in Fresh Meadows around 9 a.m and collared the pair while they were still inside the bank, according to police.

The suspects were “just passive,” according to eyewitness Lincoln Stevens a mobile technician from Queens Village, who saw the bust.

“I was coming and a cop car came from behind with its lights on,” Stevens, 26, said. “I parked and got out to watch. [The cops] go in the bank, then the bank manager and teller come out with [their] hands tied. Fifteen cop cars come. A couple of [the cops] went in with their guns out. They took the suspects out.”

He continued: “Before you realized what was happening, it was over.”

Cops could not immediately identify the robbers or provide their charges.
